Copilot for Xcode

The extension integrates GitHub Copilot, Codeium, and ChatGPT into Xcode’s source editor, offering on‑the‑fly code suggestions, chat‑based assistance, and automated code modifications. It runs as a background service that communicates with the selected language‑model provider, allowing developers to request completions, ask questions, or apply custom commands directly from the editor.

Target users are macOS developers who work in Xcode and want AI‑driven assistance without leaving the IDE. The tool requires a public network connection, appropriate API keys or subscriptions for the chosen model, and standard macOS permissions such as folder access and Accessibility API access.

Installation is performed via Homebrew or a manual download, followed by enabling the source‑editor extension in System Settings and granting the necessary permissions. The extension supports configurable key bindings, global hotkeys, and custom commands, and it provides separate setup steps for each supported AI service.
